Very nice. I'm in the process of planning a basement brewery and am trying to decide on whether to use natural gas or electric. You don't run into any carbon monoxide issues with the propane? Does the exhaust fan have enough oomph to pull it all out? Do you also have a fresh air intake somewhere? Just curious as I start to plan...
You will want to provide some makeup air... in some fashion. Essentially, the hood is going to pull 300 to 400 CFM (I am estimating based on experiance in the HVAC industry, different hoods may pull even more). It
will get that from somewhere. If you provide a duct to the outside, it will pull it form that duct. If not, it will pull it through window seals or cracks in the exterior of the house. Essentially creating colder/wamer exterior rooms.
With that said, most modern furnaces have a duct leading to the outside already located near the furnace to prevent the furnace exhaust and hot water heater exhaust from doing that exact same thing... so you many not need to add one if that already exists in your brewing area.
Bottom line, the makeup air source is not 100% needed, but I highly recommend it.
Now for the important part... does the jenair hood prevent the brewing smell from permiating the house? That issue has pushed me to the garage in my house, and I would love to return to the friendly confines of the basement myself!!
Thanks,
